Be it known that I, SAMUEL WARD, of Amsterdam, in the county of Montgomery, and State of New York, have invented-a new and improved Take-Up for Knitting Machines and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawings, .forming part of this specification.

The present invention relates to a novel arrangement of mechanical devices for the take-up of knitting machines, which is of such a nature that the tension upon the fabric knit in the machine will regulate the action of the take-up, as will be apparent from the following detail description of the same, reference being had to the accompanying plate of drawings, in which- A Figure 1 isan elevation of one end of the frame in which. the take-up is arranged Figure 2, a plan or top view of the same; and

Figure 3, a transverse vertical section, taken in the plane of the line 2 x, fig. 2.

Similar letters of reference-indicate like parts.

A, in the drawings, represents'the frame, in which the take-up devices are arranged, this frame being hung by its upper horizontal cross-bar B so as to freely turn upon a centre pin or red, C, secured in the outer end of the horizontal arm or beam D, projecting from the upright or post E. In this frame, at its lower end, two

rollers, F, are hung, so as to turn with one above the other, but not in the same line with, each other, both being geared togetherat one end, through similar gear or cog-wheels G. H, a ratchet-wheel, secured to the opposite end of the upper roller F to that at which the cog-wheel G' is secured to it, this ratchet-wheel being upon the outside of the frame A. I, a pawl, hung to the lower end of a lever-rod, J, so as to engage with the teeth of the said ratchet-wheel H, the rod J extending upward toward the upper end of the frame A, along the outside of one of the end pieces of such frame, turning upon a fulcrum or centre at K. The upper end of the lever-rod J is hung to the outer end of a bank-arm, L, of a rocker-shaft, M, hung in suitable. bearings of the frame A, aboveits upper cross-bar B, along and in a parallel direction with which it extends toward the centre spindle C, upon which the frame turns. The inner end of the rock-shaft-M is provided with a crank arm, N,

thfi, by the friction-wheel or roller,(), secured in its outer end, bears against and travels upon the cam-shaped edge or flange P, formed around the under side of a horizontal circular disk or plate, Q, secured to the said centre spindle C. R, a spiral spring, connected with the shaft-crank L, to secure its proper operation- A By the above-described arrangement and connection of parts between the two rollers F and the stationary cam-disk Q, it is,pla3in to be seen that, as thcframe A turns upon its centre spindle, the said rollers will be intermittently revolved, so that, if the fabric knitted in the machine be properly passed to and about the said rollers, as shown by a red line in fig. 3 of the drawings, for instance, to the beam or roller upon which it is to be wound, (which latter roller it is intended to hang in the frame above the upper roller F so as to rest upon 115,) the knitted fabric, as it is knit in the machine, will be taken up thereby, 'as'is obvious without any further explanation. I i

In lieu of passing the knitted fabric directly to the rollers F from the knitting cylinder of the machine, I pass it over a roller, S, hung in and between arms T suspended to the side pieces of the turning frameA, which arms are connected with spipal springs U; the tendency of which is to hold them up and to counteract the downward strain upon the roller S, produced by the tension of the knitted fabric passing over it to the rollers F. V is a latch, hung to one of the side pieces of the frame A, which latch, through a wire, W, is con: nected with one of the arms T, so that when-such arm is depressed by the tension of the knitted fabric acting upon the roller S, hung to such arm, the said latch will be swung or pulled down, and thus being brought to bear against the arm X of the pawl-carrying rod J, will swing said rod in such manner upon its fulcrum as to prevent its pawl from acting upon the teeth of the ratchet-wheel ina proportionate decree, whereby the taking up of the knitted fabric by the rollers F is correspondingly decreased or diminished.

Thus, from the above description, it is plain to be understood that, as the tension upon the knitted fabric being taken up by the rollers F, acts upon the roller S, about which it passes to them, if such tension exceeds that of the springs U, connected with the arms T, carrying such roller S, such roller will be depressed, and this, through its arms '1, the latch V brought to bear in such a manner as to put the ratchet-pawl out of operation, either more or less, indirect proportion' thereto, correspondingly decreasing the take-up motion of the knitted fabric, whereby, as is obvious. the take-up of the knitted fabric is regulated, and always kept or maintained u iiform and even.

I claim as new, and desire to seeure b'y Letters Patent, is

1. The rollers F, geared together at one end, and hung in a. revolving frame A, ratchet-wheel H, pawl I, lever-arm J X, rocker-shaftM, with crank-arms L end N, and stationery cam-disk Q, when "all arranged together so asto operate substantially as'and for the purpose described.

2; In combination with the above, I claim the tension roller S, so urrahged in the frame A, and with regard to the levr-carryihgpawl I, as to operate substantially in the manner and for the purpose specified.

SAMUEL WARD.
